power is shown in Fig. 124. In Fig. 125 is shown a power 

 outfit, the machinery being covered for protection. Many 

 other efficient spraying outfits are in use, but these 

 three will serve to illustrate the kind of work that is 

 needed. Until ten or fifteen years ago, the greater number 

 of fruit-growers used an ordinary wagon, with box or 

 rack, and a single fifty-gallon barrel, and this outfit may 

 still be seen; but this is found to be both uneconomical 

 and ineffective for large operations. 



The use of long pieces of 3^-inch gas-pipe, with the 

 nozzle attached to the end, is advisable when one is work- 

 ing in the tops of the trees, but they are^likely to be a 

 nuisance if one works from the ground. Th^ are awkward 

 if more than 10 feet 

 long. Growers usu- 

 ally prefer to use a 

 bamboo fishing-pole, 

 and to secure the 

 hose near its upper 

 end, letting the lower 

 part of the pole re- 

 main free. Most 

 operators use insuffi- 

 cient hose. For work 

 in old orchards, the 

 run should be at 

 least 15 feet long. 



For yards and 

 ornamental plants, a 

 cart-like rig, like that 

 shown in Fig 126, is 

 handy and efficient.
